WILLIAM HENERY STONE, 0F PORT ANGELES,

AIR-COOLER.

Be it known that I, WiLLIAM H. STONE, a citizen of the United States, and a resident of Port Angeles, in the countyof Clallam and State of Washington, have invented a Air-Cooler', of which the following is a full, clear, and exact description.

yThis invention relates to improvements in air coolers, an object of the invention being to provide an improvedapparatus vfor cooling the air in circulation in a house or room during hot weather. v

A further object is to provide an improved apparatus through which the air is compelled to take a circuitous pathand pass through screens over which cold water flows, and'over saturated cloths or other moisture holding pads to cool the air which iinally escapes through an ice chamber and is directed to any point of use. p

A further object is to provide an air cooling ap aratus which can be manuiactured d at a reasonably low price, and which can be economically operated to maintain a low temperature.

With these and other objects in view the invention consists in certain novel features of construction, and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawings- Figure 1 is a view i longitudinal vertical section illustrating my improved apparatus, the section being taken on the line 1-1 of Fig. 2.

Fig.` 2 is aview mainly in vertical section, but partly in rontelevation of my improved apparatus.

1 represents a casing which is preferably supported on a suitable base 2. `This casing 1 is divided by a vertical series of superimis compelled to pass posed partitions or slush boards 3, said partitions extending to one edge of the casing andspaced from the other edge of the casing andV having a staggered arrangement so as to compel the air to take a oircuitous path upwardly between said partitions as indicated by the arrows in Fig. 1.

Wire mesh or other form of screens 4 are located in the casing and connect the free ends of the partitions with the inner fixed ends of the partitions below so that the air through said screens. On the uppermost partition 3 an ice pan 5 Specication of Letters Patent. I

is located and is provided with perforations 6 at one end throughwhioh the water from the melting ice passesv over the partition onto the screen 4 below and thence downwardly through the casing. This pan 5 is adapted to contain a blockV or blocks ofv ice 7 and the partitions -below the ice pan supporting partition are provided with moisture holding pads 8, which ma. be of cloth or any other suitable materiai, which becomes saturated with the water, .an-d by evaporation gives 0H the water to the air as the latter passes over said pads.

A door 10 is provided in the front of the casing giving admission to the upper portion of the casing for the insertion and ref moval of the ice. 11 represents an air inlet pipe which preferably extends along one wall of the casing 1 and communicates at its lower end with the casing 1 through the medium of a port 12.

13 represents a fan or blower casing which is connected by a pipe 14 withan outlet port 15 in the upper portion of the casing, preferably adjacent thevice pan, as clearly indicated in Fig. 1. In this fan or blower casing 18 a rotary or other form of blower- 16 is provided for discharging the air throu' h an outlet 17 t0 any desired point of use, and I illustrate an electric motor (18 for driving the fan or blower, although, of course, this fan or blower may be operated in any desired way.

In operation, the heated air circulates downwardly through the pipe 11, through port 12, and thence between the series of partitions 3, through the screens 4 and over the pads 8, thus causing a reduction of temperature of the air, and said .air as it reaches the upper portion of the casing is cool and finally asses in direct contact with the ice 7 and t ence through the outlet'pipe 14 and blower casing 13, the circulation being induced by. the fan or blower A16 as will be readily understood.

It is obvious that instead of employing a piece of ice 7, a cooling liquid or other ht be'located in the pan 5 to supp ly the 4 and l Patented Sept. .20, 1921. Application med. June 8, 1920. Serial Nm 387,353.

agent pads 8, and a drain cock 18 communicates with the lower portion of the casing to remove any excessive drip therein.

Various slight changes might be made in the general form andarrangement of parts described without departing from the invention, and hence I do not limit myself to v 4myself at liberty to make such changes and ture ho 2 1,391,595;l the precise details set forth, but consider ing sta red relation to each other, moiscgling screens connecting the partialterations as fairly fall within the spirit tions and through which the airis compelled 10 and scope of the appended claim. to pass, and moisture holding pads on the 5 I claim: partitions.

An-air cooler, comprising a casing, a series i )of superimposed partitions in the casing hav- Y WILLIAM HENERY4 STONE.
